[Dávid Bolvanský via Phabricator via llvm-commits]

xbolva00 added inline comments.

+  if (MaxLen == 1) {
+    // Fold memchr(x, y, 1) --> *x == y ? x : null for any x and y,

LenC->isOne() seems like as a good suggestion.


Then you can use..

Str = Str.substr(0, LenC->getZExtValue());


One less variable to keep in mind when reading.
